When there's a witness to Dexter Morgan in action, he inspires a copycat killer who threatens his existence in the sixth novel written by Jeff Lindsay, Double Dexter, now in print from Doubleday. The publisher has released this trailer.

Double Dexter, the sixth novel featuring serial killer Dexter Morgan (who has inspired the Showtime series focusing on the character) will be published on October 18th, but author Jeff Lindsay is concerned that people may be idolizing his creation.

Ecko|Code and Showtime Networks today announced that the Dexter Slice of Life game is now available to play on Facebook. Based on the hit Showtime series Dexter®, Dexter Slice of Life combines progressive "real-time stealth" gameplay with the dark humor and suspense of the TV show.

Dexter made its sixth season premiere last night, and anyone who may have been put off by a somewhat contrived fifth season was surely in for some good news; good news which has also translated into ratings growth.

Deadline caught up with Dexter's new executive producer and showrunner Scott Buck and talked to him about a number of subjects. Among them is a bit of a preview of what fans can expect when the show returns and the decision to jump forward a year.

Dexter Morgan (Michael C. Hall) spent Season Five atoning for the death of his wife, Rita. He committed to being a part of her children's lives and entered into a deep, passionate relationship with Lumen, unlike anything he'd ever had before. But Dexter's need to kill overpowers his desire for human connection.

We're still a few months away from Dexter's season six premiere, so the time seems appropriate to take a look back at the show's motion comic spin-off, Dexter: Early Cuts. This installment looks at the six-part web series "Dark Echo."

As we inch closer to the September premiere of Dexter's sixth season, more and more rumblings are being heard about what we can expect. Michael Ausiello's TV Line has a tiny bit of spoilerage for Dex among a number of other shows.

The Wrap caught up with actress Jennifer Carpenter to talk about her role as Deb, Dexter Morgan's sister, on Showtime's Dexter, offering up some hints on what may be coming in the show's sixth season - which debuts this September.

While details are slowly being released about season six of Dexter, fans caught a sequence of the series being filmed in Long Beach, California, featuring series stars Michael C. Hall and Jennifer Carpenter.

Details are scant, but Variety is reporting that Brea Grant, most recently seen in her super-speeding role on Heroes, has come aboard Dexter season six, where she'll join such guest stars as Edward James Olmos and Colin Hanks.
